There are no spaces preceding or trailing any of these elements, or in between them, so if you copy the code from this blog post, PLEASE get rid of any preceding spaces otherwise it won’t work. However, because parentheses are special wildcard characters in their own right, you need to tell Word to treat them as normal text characters and not as special characters, so you put in a backslash ‘\‘ (also known as an ‘escape’ character) before the ).
For example, type \? to find a question mark. To search for a character that's defined as a wildcard character, type a backslash (\) before the character. You can also enter a wildcard character directly in the Find what box instead of selecting an item from the Special pop-up menu.
